ELECTRICAL FIRE-LIGHTING. ATTACHMENT FOR STOVES.

Specification of Letters Patent.

Patented July 13,1920.

Application filed December 16, 1919. Serial No. 345,413.

To all whom it may concern:

Be it known that I, Trro L. BRUNELLI, a subject of the King of Italy, residing at Clearfield, in the county of Clearfield and State of Pennsylvania, have invented new and useful Improvements in Electrical Fire- Lighting Attachments for Stoves, of which the following is a specification.

The object of my present invention is the provision of a simple, compact and highly efiicient electrical fire-lighting apparatus for .use in conjunction with a cooking stove, and

through the fire-box in the plane indicated by the line 33 of Fig. 1.

Fig. 4 is a diagrammatic view showing the circuits and wiring in the cabinet of my improvement.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Comprised in the stove illustrated is a fire box 1 and a grate 2, and connected through brackets 3 with one wall 4 of the stove and arranged exteriorly of the stove is the cabinet 5 of my novel apparatus. The said cabinet 5 is provided at 6 with the exterior member of a push-button circuit closer indicated by 7 It will also be noted by I reference to Fig. 1 that the cabinet 5 is provided with a depending conduit 8. The said conduit 8 eXtends downwardly into a casing 9, fixedly connected to the stove wall 4, but electrically isolated therefrom, by sections 10 of insulating material, which bridge an opening-11 in the said wall 4. At 12 is an electrode, having at 13 a head or enlargement which rests in closeproximity to but is separated by gaps 14 from portions of the grate 2, as appears in Figs. 1 and 3.

The said electrode 12- is provided with a lower arm which reaches laterally outward through the insulating sections 10 and terconduit 21,-

minates within the casing 9, where it is electrically connected through the medium of an angular conductor 15 with a wire 16 of the wiring in the cabinet 5. 17 of the wiring in the cabinet is brought downwardly through a supplemental conduit 18 pendent from the cabinet 5 and is electrically connected through the lower conductive bracket and -the metallic wall 4 with the grate .2. Manifestly by-virtue of the provision of the casing 9 there is little or no liability of an attendant receiving a shock by forming a short circuit between the lower conductive bracket and the source of current supply.

Connected with a source of alternating current supply are wires 19 and 20, Fig. 4, which are led into the cabinet 5 through a connected with the primary coil 21 of a stepdown transformer, located in the cabinet 5,

and the wire 20 is connected with one mem-' ber of the push-button 7, the other member of which push-button is also connected with the primary coil 21. The secondary coil 22 is electrically connected with the primary 23 of an induction coil, a condenser 24 and a vibrator 25, all of the said elements being located in the cabinet 5, and the con-.

denser 24 and vibrator or circuit maker and breaker 25 being designed to intensify the are between the head of the electrode 12 and the'grate 2. Also located in the cabinet 5 is the secondary 26 of the induction coil,

which, as clearly shown in Fig. 4, is connect.

ed to the before-mentioned wires 16 and 17 In the practical use of my improvement,

paper and kindling are superimposed upon the grate 2, and above the electrode head 13, and when this is done, all that is necessary in order to start. the fire, is for the attendant to press inwardly on the member 6 of the push-button 7, since when this is done an arc will be created between the head 13 and the grate 2, and in consequencethe paper will be ignited and the fire started. When desired a number of sparks or arcs may be created between the electrical head 13 and the grate by pushing the push-button member 6 inwardly a number of times in succession.

It will be appreciated from the foregoing that my attachment is so compact that it oifers but a slight exterior projection on a stove; also, that the attachment is available for use at all times, is reliable in operation,

The wire 60 Fig. 1. The said wire 19 is 75 and is devoid of delicate elements such as are likely to get out of order after a short period of use.

Having described my invention, what I claim, and desire to secure by Letters-Patent, is:

1. The combination of a stove, having a conductive wall, a grate therein in electrical connection with said wall, an electrode hav ing a portion arranged in close proximity to portions of the grate and also having an arm extending outwardly through an opening in the stove wall, insulating means connected to said wall and receiving the arm of the electrode to support the latter, a. casing connected to the said insulating means and receiving the outer end of the electrode, a cabinet fastened to the stove wall exteriorly thereof and having conduits one of which extends into the casing, conductive means connecting the other conduit and the stove wall, wires in said conduit, one of said wires being connected with said conductive means, a conductive connection arranged in the casing, and electrically connecting the other wire and the electrode, house wires extending into the cabinet and adaptedito be connected .with a source of alternating current supply, and a step-down transformer and spark intensifying means arranged in the cabinet and electrically connected with the last-named wires and the first-named wires; one of the last-named wires being also provided with a switch carried by the cabinet.

2. The combination of a stove, having a conductive wall, a grate therein in electrical connection with said wall, anelectrode having a portion arranged in close proximity to portions of the grate and also having an arm extending outwardly through an opening in the stove Wall, insulating means connected to said wall and receiving the arm of the electrode to support the latter, and means including a switch for electrically connecting the stove wall and the electrode with a source of electrical energy.

3. The combination of a stove, having a conductive wall, a grate therein in electrical connection with said wall, an electrode having a portion arranged in close proximity to portions of the grate and also having an arm extending outwardly through an opening in the stove wall, insulating means connected to said wall and receiving the arm of the electrode to support the latter, a casing connected to the said insulating means and receiving the outer end of the electrode, a cabinet fastened to the stove wall exteriorly thereof and having conduits one of which extends into the casing, conductive means connecting the other conduit and the stove wall, wires in said conduit, one of said wires being connected with said conductive means, a conductive connection arranged in the casing, and electrically connecting the other wire and the electrode, and means in the cabinet and including a switch for electrically connecting the said wires with a source of electrical energy.

In testimony whereof I affix my signature.
